Brimstone careers

The Brimstone Process™ is a breakthrough in cement production, making carbon negative portland cement with carbon-free calcium silicate rock instead of limestone. Cement made with The Brimstone Process™ is chemically and physically identical to conventional portland cement, with the same quality and performance builders have trusted for over 150 years. Simply put, our process will turn cement, one of the most intractable climate problems, into a carbon negative climate solution. It all starts with a new kind of rock.
